But when I was satisfied and generated all eight places where I wanted to have them the placement of the speaker and subject text is on different heights. Sometimes one or the other is different, sometimes both and sometimes they are the same. Is this a bug, or am I doing something wrong?As Michael Koch said: The content of the variable "text_h" depends on which characters you are printing. So I changed: drawtext= enable = 'between(t, 105, 115)': text = 'speaker': y = main_h - (text_h * 4), drawtext= enable = 'between(t, 105, 115)': text = 'subject': y = main_h - (text_h * 2.2), to: drawtext= enable = 'between(t, 105, 115)': text = 'speaker': y = main_h - 200, drawtext= enable = 'between(t, 105, 115)': text = 'subject': y = main_h - 140, That gives satisfactory results. The only problem is when the font size changes. Then I have to remember I need to change these two values also. But I do not expect that to happen often, so I can live with that.
As a workaround you could define the strings in a subtitle file and burn the subtitles into the frames.
